Bifacial solar panel power generation gain analysis Apr 01, 2022

Attenuation Advantage Analysis The power warranty of single-sided modules is 25 years: 2% attenuation in the first year, and 0.55% attenuation every year; 30-year power warranty for bifacial modules: 2% attenuation in the first year and 0.45% annual attenuation; Therefore, the double-sided module has a 0.1% annual attenuation advantage compared with the single-sided module. Taking the Shandong 10k...

The building photovoltaic outlet has reached the BIPV market space Mar 25, 2022

The promotion of distributed photovoltaics has promoted the development of building photovoltaic technology. In the past, solar photovoltaics were mainly applied in the northwest region with centralized power plants. With the promotion of photovoltaic projects to the densely populated eastern region, distributed photovoltaics began to play an increasingly important role. Among the distributed phot...
